FIELD: agriculture. SUBSTANCE: automatic temperature sensitive air vent has body formed as flanged bracket. Gate is mounted in bracket opening on rotary shaft. Drive crank is fixed on one end of rotary shaft outside body. A pack of temperature-sensitive bimetallic plates is positioned on body outer surface. Each plate has bent portion. One end of pack is coupled with fixed support on body and other end is coupled with drive crank. Return spring is also connected with its one end to fixed support and with its other end to drive crank. When ambient air temperature changes, length of bimetallic plate pack is altered and it turns gate by drive and crank. EFFECT: increased efficiency in temperature control and enhanced reliability in operation. 2 dwg
